When humans choose themselves to form an alliance with
Many strategies take into account human's egoism: for example systems which force to work for a common cause or for the economy which enables to negotiate a price depending on supply and demand with individualistic and rational « agents ».
Personally, I am interested in strategies of cooperation starting from the same presupposition: the humanbeing has both a selfish and an altruistic side. We must first seek to converge the interest and the collective interest. Worse: in case of a general conflict, someone altruistic would act for other people's interest to the detriment of his own. He would then be disadvantaged in a Darwinian sense...
Yet three pieces of information I recently aknowledged show that human being (as some animals) can do things to get something vital, that are seemingly against his interests : allying with others.
